An attribute, as used in the document, has the same sense as in
SGML and XML [XML]. Some attributes are integral to the accessibility
of content (e.g., the "alt", "title", and "longdesc" attributes in
HTML).

Information that explains or identifies a tag or element in a
markup language. Element types may have more than one attribute like
size, shape, wight and color. Some attributes are integral to the
accessibility of content (for example, the "alt", "title", and
"longdesc" attributes in HTML)

OPEN: concern that should not set size, shape, wight and color in
attributes OPEN: consider Chuck's comment OPEN: consider if need both
tag and element, or just one

Audio Descriptions

Audio description (also called "Described Video") is an equivalent
alternative that provides aural information about actions, body
language, graphics, and scene changes in a video. Audio descriptions
are commonly used by people who are blind or have low vision,
although they may also be used as a low-bandwidth equivalent on the
Web. An audio description is either a pre-recorded human voice or a
synthesized voice (recorded or automatically generated in real time).
The audio description must be synchronized with the auditory track of
a video presentation, usually during natural pauses in the auditory
track.

Authoring Tool

ATAG 2.0 defines an "authoring tool" as: any software or service
that authors may use to create or modify Web content for
publication.

Any software that is used to produce content for publishing on the
Web. Authoring tools include Web content editors, document conversion
tools, and software that generate Web content from databases.

Captions

Captions are equivalent alternatives for movie audio. Captions
consist of a text transcript of the auditory track of the movie (or
other video presentation) that is synchronized with the video and
auditory tracks. Captions are generally rendered graphically and
benefit people who can see but are deaf, hard-of-hearing, or cannot
hear the audio.

Conversion

A conversion is a process that takes, as input, Web content in one
format and produces, as output, Web content in another format
(e.g.,"Save as HTML" functions).

Device independence

Device-Independent Action
A device-independent action is not bound to only one type of input
device.

The use of a webpage or event handler without a specific kind of
input device. Scripting should be device-independent or provide
multiple input and output options for different devices.For example,
onDblClick requires a mouse; there is no keyboard equivalent for
double clicking. Input devices may include pointing devices (such as
the mouse), keyboards, braille devices, head wands, microphones, and
others.

Equivalent Alternative

An equivalent alternative is content that is an acceptable
substitute for other content that an end-user may not be able to
access. An equivalent alternative fulfills essentially the same
function or purpose as the original content upon presentation to the
end-user. Equivalent alternatives include text alternatives, which
present a text version of the information conveyed in non-text
content such as graphics and audio clips. The text alternative is
considered accessible because it can be rendered in many different
ways (e.g. as synthesized speech for individuals who have visual or
learning disabilities, as Braille for individuals who are blind, as
graphical text for individuals who are deaf or do not have a
disability). Equivalent alternatives also include "media
alternatives", which present essential audio information visually
(captions) and essential video information auditorily (audio
descriptions).

Markup language

A markup language is a syntax and/or set of rules used to manage
markup (e.g. HTML [HTML4], SVG [SVG], or MathML [MATHML]).

A markup language is a syntax and/or set of rules to manage content
and structure of a document or object (for example, HTML , SVG , or
MathML).

Repairing, Accessibility

Accessibility repairing is the process by which Web content
accessibility problems that have been identified within Web content
are resolved. ATAG 2.0 identifies three categories of repair:
Automated (i.e. the authoring tool is able to make repairs
automatically, with no author input required), Semi-Automated (i.e.
the authoring tool can provide some automated assistance to the
author in performing corrections, but the author's input is still
required before the repair can be complete) and Manual (i.e. the
authoring tool provides the author with instructions for making the
necessary correction, but does not automate the task in any
substantial way).

Transcript

Transcripts are equivalent alternatives for the sounds in an audio
clip or an auditory track of a multimedia presentation. A "collated
text transcript" for a video combines (collates) caption text with
text descriptions of video information (descriptions of the actions,
body language, graphics, and scene changes of the visual track).
